  • Patent number: 7853197
    Abstract: A satellite receiving antenna at a user location receives satellite signals at a first frequency from a satellite. The satellite signals travel along a satellite signal route encompassed within an aperture of the satellite receiving antenna. A terrestrial transmitter transmits signals at the first frequency along a wireless transmission route from the transmitter to the user location. The terrestrial transmitter is located with respect to the user location so that the wireless transmission route is outside of the aperture of the satellite receiving antenna. Also the terrestrial transmission power is controlled so that the terrestrial signals present at the user location result in terrestrial input signals from the satellite receiving antenna which are below an interference signal power level with respect to satellite input signals produced by the satellite receiving antenna. Thus, the terrestrial signals do not interfere with the satellite signals even though they are transmitted at a common frequency.

  • Patent number: 6983123
    Abstract: A satellite receiving antenna (16) at a user location (14) receives satellite signals at a first frequency from a satellite (12). The satellite signals travel along a satellite signal route (42) within a look angle about the centerline (28) of the antenna (16). A terrestrial transmitter (20) transmits signals at the first frequency along a wireless transmission route (40) from the transmitter to the user location (14). The terrestrial transmitter (20) is located with respect to the user location (14) so that the wireless transmission route (40) is at a relatively large angle to the centerline (28) of the first antenna (16). The angle of the wireless transmission route (40) to the satellite antenna centerline (28) is large enough so that the terrestrial signals present at the location (14) result in terrestrial input signals from the antenna (16) which are less than an interference level with respect to satellite input signals produced by the antenna.

  • Patent number: 6892050
    Abstract: A first antenna (16) at a user location (14) receives signals at a first frequency where the signals are travelling only within a first directional reception range as measured from a centerline (28) of the first antenna (16). The first antenna (16) has its centerline (28) aligned to receive direct broadcast satellite signals transmitted from a satellite in geosynchronous orbit about the earth. A second antenna (18) at the user location (14) receives signals at the first frequency where the signals are travelling only within a second directional reception range as measured from a centerline (30) of the second antenna (18). The second antenna (18) is aligned to receive signals transmitted at the first frequency from a terrestrial transmitting location remote from the user location. A terrestrial transmitter transmits signals at the first frequency and directionally within a terrestrial azimuth range from the terrestrial transmitting location.

  • Patent number: 6690926
    Abstract: A multiple data stream processing arrangement includes a receiver/signal processor (14) and a plurality of signal input paths (11, 12) which meet at a junction (36). A junction output from the junction (36) provides a single input to the receiver/signal processor (14). A switching arrangement (16) is associated with the plurality of signal input paths (11, 12). The switching arrangement (16) includes a switch (31, 32) connected in each signal input path (11, 12). Each switch (31, 32) responds to an enable signal to allow a data stream applied to the respective input path (11, 12) to pass on to the junction (36) and to the receiver/signal processor (14). Only one signal input path (11, 12) and respective switch (31, 32) is enabled at any given time.
